Why do Switch and ListView controls in MAUI not update with 2-way binding?

Asked 2022-Apr-11 at 09:33

This question is about two MAUI controls (Switch and ListView) - I'm asking about them both in the same question as I'm expecting the root cause of the problem to be the same for both controls. It's entirely possible that they're different problems that just share some common symptoms though. (CollectionView has similar issues, but other confounding factors that make it trickier to demonstrate.)

I'm using 2-way data binding in my MAUI app: changes to the data can either come directly from the user, or from a background polling task that checks whether the canonical data has been changed elsewhere. The problem I'm facing is that changes to the view model are not visually propagated to the Switch.IsToggled and ListView.SelectedItem properties, even though the controls do raise events showing that they've "noticed" the property changes. Other controls (e.g. Label and Checkbox) are visually updated, indicating that the view model notification is working fine and the UI itself is generally healthy.

Build environment: Visual Studio 2022 17.2.0 preview 2.1
App environment: Android, either emulator "Pixel 5 - API 30" or a real Pixel 6

The sample code is all below, but the fundamental question is whether this a bug somewhere in my code (do I need to "tell" the controls to update themselves for some reason?) or possibly a bug in MAUI (in which case I should presumably report it)?

Sample code

The sample code below can be added directly a "File new project" MAUI app (with a name of "MauiPlayground" to use the same namespaces), or it's all available from my demo code repo. Each example is independent of the other - you can try just one. (Then update App.cs to set MainPage to the right example.)

Both examples have a very simple situation: a control with two-way binding to a view-model, and a button that updates the view-model property (to simulate "the data has been modified elsewhere" in the real app). In both cases, the control remains unchanged visually.

Note that I've specified {Binding ..., Mode=TwoWay} in both cases, even though that's the default for those properties, just to be super-clear that that isn't the problem.

The ViewModelBase code is shared by both examples, and is simply a convenient way of raising INotifyPropertyChanged.PropertyChanged without any extra dependencies:

ViewModelBase.cs:

These both may be bugs with the currently released version of MAUI.

This bug was recently posted and there is already a fix for the Switch to address this issue.

You are running the project via Java 1.8 and add the --add-opens option to the runner. However Java 1.8 does not support it.

So, the first option is to use Java 11 to run the project, as Java 11 can recognize this VM option.

Another solution is to find a place where --add-opens is added and remove it. Check Run configuration in IntelliJ IDEA (VM options field) and Maven/Gradle configuration files for argLine (Maven) and jvmArgs (Gradle)

QUESTION

How to replace the bundled Dart SDK in Flutter to run natively on Apple Silicon (ARM64)?

Asked 2022-Mar-21 at 16:27

Dart SDK officially supports ARM64 and as of now, 2.14.2 is the latest (stable) Dart SDK that has support for ARM64. Though it was the same version that was bundled in my Flutter setup, it seemed to run on Intel architecture (Activity monitor shows dart processes running on Intel).

I manually tried replacing the dart SDK on my flutter installation bu replacing flutter-directory/bin/cache/dart-sdk/ with the contents of a zip file of the Dart SDK made for ARM64, downloaded from dart.dev archive. But trying to run an app on an Android emulator (which runs on ARM64 and was working on my old Flutter setup), throws this error:

It seems it can't be used with Flutter yet, as seen in:

Apple Silicon support in the Dart SDK

[...] Note that the Dart SDK bundled in the Flutter SDK doesn’t have these improvements yet.

[Announcing Dart 2.14][ScreenShot]: https://i.stack.imgur.com/N8Qcc.png

And:

Get the Dart SDK

[...] As of Flutter 1.21, the Flutter SDK includes the full Dart SDK. So if you have Flutter installed, you might not need to explicitly download the Dart SDK. Consider downloading the Dart SDK if any of the following are true:

You don’t use Flutter.

You use a pre-1.21 version of Flutter.

You want to reduce disk space requirements or download time, and your use case doesn’t require Flutter. For example, you might have a continuous integration (CI) setup that requires Dart but not Flutter.

How to configure proxy in emulators in new versions of Android Studio?

Asked 2022-Feb-23 at 14:14

Problem Description

I need to configure the proxy manually in my emulator through Android Studio. From the official Android documentation, it is suggested that this change can be made in the "settings" tab of the emulator's extended controls. The problem is that it seems to me that this documentation is outdated, as this setting is no longer displayed in the "settings" tab of the Android Studio emulators' extended controls.

ANSWER

Answered 2022-Feb-09 at 17:17

Those samples depend on JDK internals.

Looks like since JDK 9 and JDK-8152907, Math.log is no longer intrinsified into C2 intermediate representation. Instead, a direct call to a quick LIBM-backed stub is made. This is usually faster for the code that actually uses the result. Notice how measureCorrect is faster in JDK 17 output in your case.

But for JMH samples, it limits the the compiler optimizations around the Math.log, and dead code / folding samples do not work properly. The fix it to make samples that do not rely on JDK internals without a good reason, and instead use a custom written payload.

This is being done in JMH here:

QUESTION

What is 'serviceability memory category' of Native Memory Tracking?

Asked 2022-Jan-17 at 13:38

I have an java app (JDK13) running in a docker container. Recently I moved the app to JDK17 (OpenJDK17) and found a gradual increase of memory usage by docker container.

During investigation I found that the 'serviceability memory category' NMT grows constantly (15mb per an hour). I checked the page https://docs.oracle.com/en/java/javase/17/troubleshoot/diagnostic-tools.html#GUID-5EF7BB07-C903-4EBD-A9C2-EC0E44048D37 but this category is not mentioned there.

Could anyone explain what this serviceability category means and what can cause such gradual increase? Also there are some additional new memory categories comparing to JDK13. Maybe someone knows where I can read details about them.

Here is the result of command jcmd 1 VM.native_memory summary

...

ANSWER

Answered 2022-Jan-17 at 13:38

Unfortunately (?), the easiest way to know for sure what those categories map to is to look at OpenJDK source code. The NMT tag you are looking for is mtServiceability. This would show that "serviceability" are basically diagnostic interfaces in JDK/JVM: JVMTI, heap dumps, etc.

But the same kind of thing is clear from observing that stack trace sample you are showing mentions ThreadStackTrace::dump_stack_at_safepoint -- that is something that dumps the thread information, for example for jstack, heap dump, etc. If you have a suspicion for the memory leak in that code, you might try to build a MCVE demonstrating it, and submitting the bug against OpenJDK, or showing it to a fellow OpenJDK developer. You probably know better what your application is doing to cause thread dumps, focus there.

That being said, I don't see any obvious memory leaks in StackFrameInfo, neither can I reproduce any leak with stress tests, so maybe what you are seeing is "just" thread dumping over the larger and larger thread stacks. Or you capture it when thread dump is happening. Or... It is hard to say without the MCVE.

Update: After playing with MCVE, I realized that it reproduces with 17.0.1, but not with either mainline development JDK, or JDK 18 EA, or JDK 17.0.2 EA. I tested with 17.0.2 EA before, so was not seeing it, dang. Bisection between 17.0.1 and 17.0.2 EA shows it was fixed with JDK-8273902 backport. 17.0.2 releases this week, so the bug should disappear after you upgrade.
